A liquid crystal display is provided. An array structure of active device includes a substrate, a plurality of gate lines, a plurality of data lines, a plurality of active devices and a plurality of pixel electrodes thereon. Each of the pixel electrodes has several fine slits, and there is an angle included by the direction of electric field that crosses over the fine slit and the rubbing direction of liquid crystal layer. When applying voltage on the pixel electrodes, the liquid crystal molecules are to be twisted and transited from splay state into bend state rapidly. After that, the spreading elastic force between liquid crystal molecules could shorten the time of transition of the liquid crystal molecules in all pixel regions. Therefore, the optically self-compensated birefringence liquid crystal display can be warmed up faster.
